Terminal velocity is the maximum velocity (speed) attainable by an object as it falls through a fluid (air is the most common example). It occurs when the sum of the drag force (Fd) and the buoyancy is equal to the downward force of gravity (FG) acting on the object. Since the net force on the object is zero, the object has zero acceleration. WebDec 22, 2024 · For any given altitude, the terminal velocity equation is: V_t=\sqrt {\frac {2W} {\rho A C_d}} V t = ρACd2W where W is is the object's weight, ρ is the density of the gas, A is the cross sectional area of the object, and C d is the drag coefficient.

WebExample [ edit] The first equation shows that, after one second, an object will have fallen a distance of 1/2 × 9.8 × 1 2 = 4.9 m. After two seconds it will have fallen 1/2 × 9.8 × 2 2 = 19.6 m; and so on. The next-to-last equation becomes grossly inaccurate at great distances. WebTerminal velocity describes the equilibrium point in kinematics where atmospheric drag on a falling object becomes equal and opposite to the acceleration due to gravity. It depends on the object's weight, frontal area, drag coefficient and the density of the medium through which it is falling.

WebNov 19, 2024 · Use the terminal velocity formula, v = the square root of ( (2*m*g)/ (ρ*A*C)). Plug the following values into that formula to solve for v, terminal velocity. m = mass of the falling object. g = the acceleration due to gravity. On Earth this is approximately 9.8 meters per second. Terminal Velocity Watch on Previous article WebVelocity (v) is a vector quantity that measures displacement (or change in position, Δs) over the change in time (Δt), represented by the equation v = Δs/Δt. Speed (or rate, r) is a scalar quantity that measures the distance traveled (d) over the change in time (Δt), represented by the equation r = d/Δt. Created by Sal Khan.
